How do I set up a Gateway? [Hardware Essentials]

A gateway in tech-talk is a device that connects two different networks, allowing information to pass from a network to the Internet.


What is a Gateway (in energy monitoring)?

In the world of energy, a gateway is a small device that connects your energy meters with your energy software. On their own, most meters can’t talk to the internet. That’s where the gateway comes in.

The gateway completes the big puzzle of creating a complete energy tracking system and it simplifies connections.

The gateway basically talks with all your devices, gathers its data and puts it online. A gateway is a modem that you can use to communicate a hundred devices through a single point.

We love to talk about gateways like “the internet guy in the hardware gang”. The one that translates energy data into internet speak.

If all this is new to you and you’re staring at a little green box thinking where do I start…fear not! Setting up a gateway it’s actually quite simple.


How to set up a Gateway

Using our detailed step-by-step guide to set up our gateway, the DEXGate2, we’re going to summarise the basic steps that you need to set up a gateway.

Of course, each device is different, therefore, you will need to check detailed instructions for yours when the time of installation comes.How to Set Up a Gateway - DEXGate2

But this quick review will give you an idea of how simple this process really is.


1) DEXGate2 (or any gateway) connection


First off, connect the Wireless antenna to the connector under the miniUSB port.

Next, connect the DEXGate2 to the Internet either by Ethernet or GPRS/3G (only for DEXGate2-3G) and power it on by connecting it through a power supply.


2) Access the administration portal

Usually, your gateway will be configured thanks to an admin tool. We call it administrator portal. This is a very simple screen with a few parameters where you can refine and indicate your hardware, in this case, your brand new gateway, how you want it to work.

Wait a minute and connect your laptop, smartphone or tablet to the WiFi using your password.  

Open a browser, go to the link for configuration (DEXGate2 is: and enter your username and password.

Write down the device ID which will appear on the menu “Status” at your DEXGate2 or on the sticker on the device (the identifier has the format 00D09 …).
3) Internet settings

At this point, you need to set up how your gateway will connect to the Internet. This will depend on how the gateway is built and the hardware and software included on it.

For example, with our DEXGate2, there are two ways of setting up the internet connection in the gateway:

  • For Ethernet: Go to System > Ethernet and Enable DHCP or disable it and enter the configuration data of the network provided by your network administrator.
  • For GPRS/3G: Go to System>GPRS/3G, enable the connection and enter the relevant data regarding the operator of the SIM.


4 ) Set Date and Time

Usually you will have a way to access to the system and set up the time and date.

This is a very important step, because by setting up these parameters you will be able to make your gateway work on the same time zone as where you’re working.

Ideally, you should have an option, like with the DEXGate2, to synchronise the device through UDP port 123.

You can always select the manual mode, but this is something that we don’t recommend.


5 ) Register DEXGate2 in DEXCell Energy Manager

The next step is what we call the “registration” process, which can be done before or after installing the device.

What will you have to do at this point? It’s one of the simplest steps when setting up a gateway.

Just access DEXCell Energy Manager and Register a new gateway. The platform will guide you step by step to successfully finish this registration.


6) Remote access

If you have internet access, you may already have remote access to your DEXGate2 from DEXCell Energy Manager.

Go to Diagnostics > Remote Support and check whether the DEXGate2 is connected to our VPN (

If is not connected yet for remote access, click Connect.


7) Connect and configure the meters

The final stage is to configure the meters (Modbus or IEC 870-5-102). Each meter works in its own particular way, so be sure to read the meter user manual.

All done, now it’s time to enjoy and start analyzing your energy!
